This pilot-scale study evaluated pulsed electric field (PEF) processing of low-fat milk inoculated with E. coli, S. cerevisiae, or L. brevis. At 10 kV/cm and 200 kJ/L total pulse energy, the study reports multi-log microbial reductions, with >5-log reductions during storage at 200–250 kJ/L and slow regrowth over 15…

This in vitro study examined whether extremely low-frequency electromagnetic fields (ELF-EMF) affect growth of Staphylococcus aureus and Escherichia coli O157:H7. Bacterial cultures were exposed to sinusoidal homogeneous ELF-EMF at 2 or 4 mT, with frequencies of 20, 40, or 50 Hz, for 1–6 hours, and CFU were compared…
Non-linear adaptive phenomena which decrease the risk of infection after pre-exposure to radiofrequency radiation.

This animal study examined whether pre-exposure to radiofrequency radiation (from a GSM mobile phone) alters survival after subsequent Escherichia coli infection. The abstract reports higher survival in the group receiving both RF pre-exposure and bacterial challenge than in the group receiving only the bacterial…
